Application filed November 8,1910. Serial No. 591,311. I

acter of cheap but durable construction and one protecting the batteriesinclosed therein from atmospheric and other deteriorating influences toa great extent. To this end, the walls of the well are formed of woodimpregnated or indurated with a. final infusible insoluble condensationproduct of phenol or creosol and formaldehyde or other equiv alent agentcontaining the methylene radical CH If desired, the walls might becomposed of fibrous material other than wood impregnated with the abovementioned condensation product or with the said condensation productmixed with any suitable inert filling material and molded to the desiredform. Preferably, the wallstare made double to form a heat insulatingairspace between the same. H

In order that my invention may be more clearly understood, attention ishereby directed to the accompanying drawings, illustrat-ing a verticalsectionthrough a battery well embodying one form of my. invention andsunk in position in the ground.

It is well known that condensationproducts of the character abovereferred to may be used for indurating or impregnating wood or otherfibrous or cellular material and rendering the same impervious to dryrot, and resistant to acids, alkalis, and other chemical agencies. Iform the walls of my improved well'of wood impregnated with such amaterial in any known manner. For example, the wood may be soaked theingredients necessary for the formation of the condensation product andthe same.

hardened in the pores of the wood by heat, either with or without the aplication of pressure. Or the walls may be ormedof the condensation"product contain'ng any cheap filling body and molded either in anintegral structure or in'slabs which may be joined together. f

The well 1 preferably is provided with a foundation or base 2 of anysuitable material, and which may be of concrete, and with the inner andouter walls, 3 and 4 formed, as stated, preferably of wood im pregnatedwith, a phenolic condensation product, the air space 5 being providedbetween the walls when double walls are provided. Batteries may beplaced upon the shelves 6. The well may be provided with a neck 7 formedas a continuation of walls 3 and 4 and with the hinged cover 8. Also, ifdesired, a cover 9 may be seated uponthe flanged ring 10 within thelower end of neck 7 Having now described my invention, what I claim anddesire to protect by Letters Patent is as follows 1. A battery wellhaving walls of wood impregnated with a phenolic condensation product,substantially as described.

2. A battery well having "walls of fibrous material indurated with aphenolic condensat-ion product, substantially as described.

3. A battery'well having double walls of fibrous material indurated withan infusible, insoluble final phenolic condensation product and havin anair space between said walls, substantially as described.

4. A battery well having walls formed of an infusible insoluble finalphenolicconden- A sation roduct and an inert filling body, substantia 1yas described.
